The experimental-industrial study results of the process of sorption of rare-earth elements on sulfonic cation-exchange resin KU-2-8 from nitrate solutions of loparite concentrate development are presented. Values of different obtained elements are discussed. Different changes in processes are described. Reprocessing loparine raw materials in the close cycle without hydrochloric and sulfuric acid, and excess of normative sodium content in productional concentrate is possible. Keywords: ionite, sorption, loparite concentrate, rare-earth element, thorium.

SummaryThe formation of precipitates, which appeared in the body of the cation-exchange resin beds during the chemical separation of carrier-free samples from proton-irradiated cyclotron targets of more than 50 mg of rare-earth oxides, is investigated. The properties and character of this insoluble salt are discussed. A method for such a separation, which avoids the disturbing influence of a precipitate, is given. The sample produced is suitable for beta ray spectroscopy. The method described is applicable to fairly short-lived rare-earth isotopes, as the procedure can be carried out within 8 hours.
